The location of your keyboard is critical to achieve optimal comfort and prevent injury while working at the computer. Placing your keyboard on the top of the desk causes most people to reach and extend their arms to type and use the mouse. Over time this reach and extension causes serious pain and discomfort in the wrists, forearms, and shoulders.
Keyboard trays bring the keyboard to the most comfortable position for each user. This position is usually slightly above the lap while the user is seated back supported in the chair. The most important feature is the ability to adjust the height and the angle of tilt independently.
